Sion: the local picture for GST Services
Sion lies in Mumbai City district, Maharashtra. Its business mix is typical of a residential neighbourhood with shops, clinics and home-based businesses. Nearby areas we also serve include Mahim, Matunga, Dadar East and Wadala. We serve clients in Sion from our Mumbai office at Workafella, Goregaon West. Freelancers and small businesses here usually ask whether they need to register at all; below the threshold, registration is optional unless you sell goods inter-state. GSTINs in Maharashtra begin with state code 27; state-tax administration is with the Maharashtra GST Department, and the central-tax office is the one named on your registration certificate.
What is GST compliance?
GST is charged on supplies of goods and services. Once registered, a business files monthly or quarterly returns, reconciles its input tax credit with suppliers' data, and files an annual return.
Which returns are filed, and when?
Regular taxpayers file GSTR-1 for outward supplies and GSTR-3B for tax payment — monthly, or quarterly under the QRMP scheme if turnover is up to ₹5 crore. The annual return GSTR-9 is optional up to ₹2 crore of turnover, and the self-certified reconciliation GSTR-9C is needed above ₹5 crore. E-invoicing applies above ₹5 crore of turnover, and an e-way bill is needed to move goods worth more than ₹50,000.
How do we keep input credit safe?
Credit is allowed only if the supplier has reported the invoice and it appears in your GSTR-2B (section 16(2)(aa)). We use the Invoice Management System to accept, reject or keep supplier invoices pending each month, and follow up unreported invoices before the return, which avoids most mismatch notices.
